If you do it should make you feel a heck of a lot better. Today I was changing the fuel filter and oil/ oil filter on my mom's 05 Cummins and then for comparisons sake I crawled under my superduty after I was done. As much as I love the cummins motor I will never own a dodge product. The steering linkage and radius arms and just everything under neath seems to be a few notches below the quality of the ford frame. I always knew the body panels on it were junk and thought the drive line was pretty close but I am much more comfortable driving my ford around.
